If you're new to programming in Ruby, here are the 3 tools you must know.



The Ruby debugging tool can be found in the library file to debug. RB. This tool will let you run your program one instruction at a time, with pauses in between. At every pause, you can examine the values or variables of your code, locate your position in a series of nested commands, and/or resume execution. You can also tell the debugger when to stop, more commonly known as breakpoints.

Using a debugger varies from programmer to programmer. Just because a debugging facility is available for Ruby, it doesn't mean that a novice programmer should quickly adapt himself to using it at once. There are programmers who are comfortable using a debugger, some aren't. It's a matter of preference but at any rate, it's nice to know that there's a tool available for Ruby.



Eventually, when you start writing longer programs, you'll want to measure how much resources, especially time, is used up by parts of your program or as a whole. This is called profiling.

You can do profiling using the command $ ruby -r profile c2fi.RB Profiling identifies the areas in your program that are using up lots of the system resources. Having identified these areas, you need to re-code your program to make it run efficiently.



Probably the coolest tool of them all, Ruby provides you with a program called ERb (Embedded Ruby), which allows you to put Ruby code inside an HTML file. You get to embed Ruby inside non-Ruby and interprets the whole thing as program input.

Ruby on Rails is becoming a popular choice for many programmers in India. Cryptex Technologies is having an experts team of Ruby on Rails Developers in India and delivers a bug-free web app as well as a mobile app.
